Positioning the unit
The Danfoss Vent heat recovery unit is designed to be hung on a wall next to the rock heat pump.
Alternatively the unit can be placed at attic level in the house. If placing the Danfoss Vent heat recovery
unit at attic level, note the freezing risk to the condensation outlet. Danfoss Vent must not be mounted on
walls adjoining bedrooms.

ments, using extracted air ducts.
Air from pool rooms containing chlorine must not be connected to Danfoss Vent.
Kitchen flues must not be connected to the unit.
Air handling system group B according to high current regulations.
The duct system must fulfil leak class B.
The exhaust air duct and extracted air duct must be installed with silencers before being connected to the
unit.
The extracted air duct must be routed from the unit to its own roof outlet on the external roof or to an
external wall vent.
Danfoss Vent can ventilate houses of up to 250 m2 or to a maximum of 90 l/s.
Duct insulation
Extracted air ducts in hot spaces do not have to be insulated while exhaust air ducts must be condensation
insulated in cold and hot spaces. Extracted air ducts in cold spaces must be insulated.
